在Retrofit连接中出错

Question

我的界面

@POST("/insert.php")
void  login(Callback<Response> callback);

Java代码

Retrofit adapter = new Retrofit.Builder()
                       .baseUrl(ROOT_URL) //Setting the Root URL
                       .addConverterFactory(GsonConverterFactory.create())
                       .build(); //Finally building the adapter

Register_Retrofit api = adapter.create(Register_Retrofit.class);


api.login( new Callback<Response>() {
    public void onResponse(Call<Response> call, Response<Response> response) {

    }

    public void onFailure(Call<Response> call, Throwable t) {

    }

});

Answer 1

您的登录方法返回void，因此您需要像这样定义：

@POST("/insert.php")
Call<Void> login();

然后，要调用login方法，请尝试：

Retrofit adapter = new Retrofit.Builder()
                       .baseUrl(ROOT_URL) //Setting the Root URL
                       .addConverterFactory(GsonConverterFactory.create())
                       .build(); //Finally building the adapter

Register_Retrofit api = adapter.create(Register_Retrofit.class);
Call<Void> loginCall = api.login();
loginCall.enqueue(new Callback<Void>() { 
     public void onResponse(Call<Void> call, Response<Void> response) { 
          ... 
     } 

     public void onFailure(Call<Void> call, Throwable t) { 
          ... 
     }
});
